March weather review: Blizzards, a tornado, and unusual warmth

Last month brought Iowa's first tornado of 2025 and exceptional March heat.

EARLY ON APRIL FOOL’S DAY. TODD, WE ARE GETTING TOWARDS THE END OF THE MONTH OF MARCH HERE. BEEN KIND OF A LOT GOING ON TEMPERATURE WISE. OVERALL, IT’S ACTUALLY BEEN PRETTY WARM. NOT TOO MANY OF THESE LIGHT BLUE COLORED TILES ON OUR TEMPERATURE CALENDAR MEANS BELOW AVERAGE DAYS. WE ACTUALLY HAD TWO RECORD HIGHS HERE IN THE DES MOINES METRO, AND A LOT OF WARMTH GENERALLY THROUGH THE MONTH. A LOT OF VOLATILITY, THOUGH OBVIOUSLY PARTS OF THE STATE HAD TWO DIFFERENT BLIZZARDS. WE HAD SOME RECORD WARMTH. THIS IS GOING TO END UP BE A PRETTY WARM RECORD, A PRETTY WARM MONTH OVERALL. IRONICALLY, THOUGH, A LOT OF US HAD MORE SNOW HERE IN THIS MONTH THAN WE DID BACK IN JANUARY. BY THE WAY, WE DID ALSO HAVE OUR FIRST TORNADO IN IOWA OF 2025 BACK A COUPLE OF FRIDAYS AGO WHEN WE HAD THOSE STRONG THUNDERSTORMS BACK ON MARCH 14TH OVER IN EASTERN IOWA BETWEEN IOWA CITY AND DAVENPORT, NEAR THE LITTLE TOWN OF WILTON, JUST OFF OF I-80. THERE, THERE WAS A VERY BRIEF TORNADO HERE LATE ON FRIDAY EVENING. EF ONE. SO EF ZERO, I SHOULD SAY, NOT THAT STRONG 85 MILE PER HOUR WINDS ONLY WENT ABOUT TWO MILES, WAS ABOUT 50 YARDS WIDE AT ITS WIDEST. HIT SOME OUTBUILDINGS AND DID SOME ROOF DAMAGE
